Question

我最近遇到过一个我之前没有的问题...... 运行react-native link会导致代码被添加到已添加的android文件中（尝试链接已经链接的依赖项。有什么想法会发生这种情况吗？

"dependencies": {
      "lodash": "^4.17.4",
      "react": "16.2.0",
      "react-native": "0.52.3",
      "react-native-blur": "^3.2.2",
      "react-native-fabric": "^0.5.1",
      "react-native-fbsdk": "^0.7.0",
      "react-native-firebase": "^3.3.1",
      "react-native-iap": "^0.2.17",
      "react-native-loading-spinner-overlay": "^0.5.2",
      "react-native-mail": "^3.0.5",
      "react-native-onesignal": "^3.0.9",
      "react-native-sound": "^0.10.9",
      "react-native-splash-screen": "^3.0.6",
      "react-navigation": "^1.0.0-beta.23",
      "react-redux": "^5.0.6",
      "redux": "^3.7.2",
      "redux-action-listeners": "^1.0.2",
      "redux-thunk": "^2.2.0"
  },

Answer 1

此错误是由于此行中文件link.js中的错误代码造成的。

const isInstalled = linkConfig.isInstalled(project[platform], dependency.config[platform]);

由commit修复，最新link.js也有固定代码，由此行替换

const isInstalled = linkConfig.isInstalled(project[platform], dependency.name, dependency.config[platform]);

这是指向issue

Answer 2

正如Pritish所提到的，在本机调用react-native link链接或重新链接所有android库时存在一个问题，这意味着它将调用与您的依赖项关联的链接脚本。解决方案是通过调用react-native link <LIBRARY_NAME>来链接新添加的库。

例如

如果您在项目中使用react-native-camera，则react-native-fs调用react-native link会同时关联react-native-camera和react-native-fs。

现在假设您已经关联react-native-camera而您没有添加react-native-fs。将react-native-fs作为依赖项添加后，如果您希望将其链接（不重新链接react-native-camera），请致电：react-native link react-native-fs

希望它有所帮助。

Answer 3

如果之前命令 react-native link 已被命中，则所有依赖项将被添加两次。

为了避免这种总是特定的链接库，如下所示：
react-native link＆lt;您的图书馆名称＆gt;

要删除重复的依赖项，请从以下文件中删除重复的条目：
   1. build.gradle（检查依赖性）
   2. setting.gradle
   3. MainApplication.java（检查导入和getPackages（））

react-native链接导致重新链接（Android）
